How 2 Modify 2 make it Fast on the Drag

[dikwan]

Hi Guys....

I'm new in this community....

I would like to ask how to make the engine run faster.....

Ex. 4 drag racing.....

What I need is the calculation of the port n polish size 4 the engine.... and also % of the reduction weight 4 the flywhell.....

and what should i do next afterward...... beside remaping the ECU...

my car is 1992 PGMFI 1.6 Honda Civic

Thanks 4 the attention guys....

Regards,
Dikwan

slicks or drag radials. Drag is all about traction (for the most part). Adjustable shocks, 900 pound drag springs in the rear, and adjustable shocks should give u a good start. The engine well.... Do u want to go boost, all motor, nitrous or what? Or engine swap to get u there faster? There are advantages and disadvantages to everything that u plan on doing.

LSD, slicks, forced induction

Shut up you guys! don't listen to them, lol;)

...yea, phatty turbo on a nicely built strong engine: rods, low comp pistons (depending on car), sleeves, streghthen all those lil moving parts in the head: vlave springs, retainers, maybe some turbo cams, with a rev hard kit.

So 20k later you can have a car that runs as fast as a mustang that cost 6k...

I'm not saying you CAN'T drag race with a civic... I'm saying you're a money burning dumbass if you do... J/K. sortof.

It's FWD it's just not suited for drag racing... ALL the weight of your car gets dumped onto the rearwheels... why not take advantage of that and use a RWD car...

Hell if you want a fourbanger...

buy a turbo 4cyl mustang... or a AWD talon/eclipse (you can keep it that way or convert it to RWD) or a miata.. or a 240...

Drag cars that are FWD cost more for less fun at the strip.

LSD,slicks,weight reduction to name a few....

turbo/super charger route would be a good way..turn up the boost at the track and down for daily driving....

Diff strokes for diff folks.....;)

[nonovurbizniz]

weight reduction isn't going to make your civic ANY faster..

100lbs roughly equals .1 secs in the 1/4 mile.

There isn't more than 500lbs of extra weight in a civic... I'd be suprised if it was even near that... that's a whole .5 secs in the 1/4... SWEET. now it's a 16 flat 1/4mi. ripper.

And to the poster...

You can port your head till there's nothing left to it... it's not going to make the car significantly faster... same goes for reducing the weight of the flywheel... it will help and it will get quicker...

But that and a 50shot should net you about 52 more hp.

If you really want to drag your civic then I'd expect to spend lots and end up with not that much.

Your best bet for cheap LARGE increases is a turbo...

check this site out...

and here's a link to a guy on H-T who sells piston/rod combos that with NO other internal mods allow you to run in the neiborhood of 16-18psi... 20+ if you put on a thicker headgasket.

how the hell all the weight on a fwd car gos on the rear wheels. last time i checked the best weight distribution for a fwd car was 52/48 f/r and your run of the mill honda runs to like 56/44 weight distribution

Dude..... i just wanna post whore on this thread.... I dont know where to start on the subject..... lol

really? Hmm how about a D16Z6 h/I/e, Phantom Grip LSD, 10 pound flywheel, on 15" rims with Pirelli Z rated tires running 14.8 @ 94 MPH, with a 2.20 foot time? Did I mention my car weighs 1960 pounds on the scales at the track? Head porting not giving u much power? Say what? Are u crazy?

making all that power is nice. Too bad u wont be able to put it to the ground with no suspension mods or drag radials. Not a very good formual for dragging to be honest.

just a bit over exagerated. for 20 K u can have one hell of a Civic. Dont know how fast u can go with that amount. But I think that a 10 second Civic is definately capable. Who knows maybe faster. I mean people have gone low 13's for 5K for crying out loud.

Your right though. RWD's are easier. I like a challenge to be honest. I like to piss off those damn rednecks with their camaros who think that an import is nothing. Besides who wants a Camaro or a Mustang when everyone has a 500 horsepower one sitting in their backyard?? Building a hybrid to me is about being different. Being unique. Not to mention the imports do bring some advantages over the domestics. Like gas mileage, handling, and reliability to be a few. I mean look at me. I had a 12 second Trans Am. It ran 12.95's on slicks. Now look what I drive! Sorry just got tired of american cars.

ummm right...thats why with out one you have rubber down the right right side of the car and with one its down both sides(double the traction, that must be bad). maybe your POS phantom grip wannabe lsd doesnt do anything but a real one does.

[sohc_vtec 2NR]

i think if your making around 250 WHP a LSD would be a necessity... i mean what good is the 250 HP if you can't put it down to the ground.... the same principle applies when your doing a nice suspension setup...

brand new the phantom grip works just as well as the quaife in the straight line. Which in reality is only a few tenths at best. Dont get me wrong it makes a bit of difference. But other modifications are by far a better bang for your dollars. For a straight line run u are better off spending money else where before u get to that point.

[AzCivic]

well its only working during the launch, what do you expect?

there is no real set hp. The LSD really gives u a bigger difference in road racing or autocross. The LSD (especially the Quaife ATB LSD) pulls u out of corners like u wouldnt believe. Just think of a slingshot. The difference on the course between an open diff and on an LSD car is like a freakin sling shot. It is soo much fun on the race course!

that'd be the real reason i got mine.

yes thats obvious. Like I said, it doesnt really help that much in a front wheel drive car when it comes to straight line. Notice I said "not that much". I never said it didnt help at all. The problem with the FWD is the weight transfer on the launch obviously. The LSD isnt that effective when u have weight transfering off the front tires to the rear. U have other problems that need to be addressed before a LSD will be worth it to use on a FWD drag car.

for a street car that u want to handle as well as be fast it definately is one of the best mods u can do. no doubt.

i say double your traction with a LSD then do one or more of the following: (copy&pasted from http://www.intense-racing.com/suspension.doc)

·Stiffer springs – Stiffer springs will allow less body movement thus resisting the center of gravity from moving rearwards.
·Stiffer struts – Aftermarket struts with a higher damping rate will also control and reduce body movement during a launch
·Lower the front only – This biases more weight to the front wheels effectively moving the center of gravity forward.
·Taller rear tires – Some people run 28” skinnies in the back to bias more weight forward.
·Run high air pressure (within the tire manufacturer’s specs) in the back tires. Besides giving you a lower rolling resistance, it will also raise the rear slightly more.
·Spring blockers in the rear.

lets not forget Z10 radius arms or similar traction bars, but I think u got pretty much everything else covered.

That's when it's PARKED... when you hit the gas and get going... damn near ALL the weight of the car gets shifted onto the rear wheels... that's why RWD cars with enough power do wheelies... ALL the weight is literally on the rear wheels...

You've never noticed the back end of cars dip down when you hit the gas? It's because the weight is being shifted from the front to the back.

Are you kidding? 15 sec quater mile with a 2.2 60ft... and that's "power"????

P.S. phantom grip lsd's are a waste of money as they will force your differential to tear itself apart.

And if you think porting your head gives you any power on an otherwise non-modded car you're a retard. You NEED a cam or turbo to force/allow more air in... porting an otherwise stock head is like putting a larger TB on... it's stupid.

it wasnt a 15 second quarter mile. get your eyes checked, it was 14.8. If u ever pay attention to Et times u would understand it is decent on the mods that I had done. BTW I never said it was power, not once. It is decent considering I ran on Z rated street radials. How many D16Z hatches with no internal mods with no forced induction run that ET with just bolt ons and no drag radials? None that I know. As a matter of fact I destroyed a B16 CRX at the track. Imagine that. U can reduce the weight of the Civic hatchback 200 pounds without a problem. I did. Who knows on a coupe. If u ever go to the track the 2.20 ET is not to bad considering the tires I was running on. Pirelli P7000's if u are curious. I have never seen an ITR(or any other hond for that matter) run better than a 2.35 on normal street tires. Nuff said. The Phantom grip doesnt tear apart the ring and pinion gears. WTF are u smoking? The phantom grip just wears out fast. The springs in them just wear out from heat, and abuse. Other than that brand new they work just fine. It takes about a year for the Phantom Grip (atleast in my experience). The Civic Si for that year runs 16.0's. The weight reduction u are talking about (.1 second for 100 pounds is just a rough estimate). I never said that porting a stock engine was worth it. Never a stock engine. Porting will make a big difference on a mildly modified engine, even a i/h/e. U said it wont make a difference. If u dont believe me. Why dont u call DPR? Go ask them. Obviously its about combination. Any moron knows that. BTW a cam doesnt "force air". U need to study a bit more on what it actually does.

P.S. bottom line is weight reduction will make your car faster. U cant just say 500 pounds and 5 tenths. That is just a rough estimate. I ran a 14.8 on a little D16. To be honest I dont know how much of a different it makes, but it does make a difference in ET's. As far as price for dollar goes. Take the CAI. It is known to be the best bang for the buck mod. What does it give u like 2 or 3 tenths in the quarter over stock? For what 200 dollars(for AEM)? Ok so how does like 2 to 4 tenths (200 pound weight reduction in a hatch) sound for free? Ring any bells????? Hmm I think it does make a difference. The head porting lets not even get started on that.....
